If you are experiencing coughing with colored secretions for nearly a month, it is recommended to consult a doctor for a more thorough evaluation. Colored secretions could indicate an ongoing infection. You can try using a saline solution to clean your nose, taking Tylenol for pain and fever, drinking plenty of water, getting plenty of rest, gargling with saltwater for a sore throat, and using honey to soothe your throat. These non-pharmacological measures can help alleviate your symptoms while you try to schedule a medical appointment.
